5 like, and particularly relates to means for attaching suchbarriers rigidly to each other or to a supporting wall.

One object of the invention is to provide for rigidly attaching to each other two angularly disposed barriers each comprised of a tier of insulating slabs or panels and to establish such connection without extending anv securinq members entirely through either i of the panels. 7

Another object of the invention is to secure in adjacent portions of insulating panels or slabs projecting headed members adapted to extend into a layer of cement or the like arranged etween vertical faces of said panels whereby said projections and an intervening layer of cement jointly establish a connection between the panels.

Another object is to arrange a layer of cement or the like between the abutting faces of two barriers each comprising a tier of insulating slabsor panels, and extend into said layer anchorage members carried bythe panels of both of said barriers, and to additionally connect said barriers by fastening elements extending transversely of said cement layers between panels of the two bar- I riers and rigidly secured to both barriers.

These and various other objects the invention attains by the construction hereinafter described and illustrated int-he accompanying drawings, wherein z- Figure 1 is a view in elevation and partial section of a pair of composite insulating barriers rigidly connected in angularly disposed relation in accordance with this invention.

showing a bracket carried thereby for engagement with another panel.

Figure 5 is a view in elevation and partial section of still another alternative form of the invention. v

Figure 6 is a fragmentary sectional view taken upon the line 66 of Figure 5.

Figure 7 is a fragmentary perspective view disclosing certain details of the structure illustrated in Figures 5 and 6, and

Figure 8 is a fragmentary perspective View of themodification shown in Figures 1 and 2.

In these views the reference character 1 designates a barrier formed by a tier of insulating slabs or panels arranged on edge, and 2 designates a composite barrier of similar construction angularly disposed relatively to the barrier 1 and rigidly connected to the latter. Between the adjoining panels of each of said barriers there are arranged layers 3 of cement or mortar tending to give rigidity to the composite structures and a layer of cement a is also provided between the abutting side face of the barrier 1 and edge face of the barrier 2. In order to very securely anchor the panels of both barriers to the-interposed layer of cement 4 it is preferred to secure into each of said panels a plurality of headed pins, screws, or other anchorage members 5, the headed ends whereof project sufficiently into the binding layer of cement to very firmly anchor both barriers to said layer when the cement has hardened.

In establishing the described connection between two barriers the same are preferably spaced apart a distance equal to the desired thickness of the intervening cement layer, and temporary forms (not shown) are put in place to retain cement-poured into said space To give additional strength to the connectio'n'thus established between the two abutting barriers it is preferred to extend metal strips 6 through "the cement layers i in the joints between the panels of the two barriers and to rigidly secure said strips to the underlyingzpanels of said barriers by nails 7 or the like, the strips 6 being of lesser width than the panels'and arranged so that they will'be completely covered by'cement during the erection of the barrier, leaving no exposed metal at the surface of the barriers.

In the construction, far as described and as illustrated in Figure 1, the joints between panels of the two barriers are in registration so that the connecting strips 6 may e. tcnd between adjoining panels of both bar riers. hen, as is illustratcl in Figure 3, the joints of the panels oil one barrier are staggered vertically with re pect to lllOetf ot the other, the described stri 6 are regl:w d by bracket members 8 of angular form which members may be secured by nails 9 or the like, to the top edges of the panels oi one of the barriers and to a side face oi the other barrier. In order that the pins 5 may be more securely held in the panelsv l and 2, and also that said pins may have a better anchorage in the cement layer 4 it is preferred to annularly or spirally corrugate said pins as exemplified in Figure 3a.

The construction disclosed in Figures 5, 6, and 7 differs from that illustrated in Figure 1 only as regards substitution for the described. members 6 of cylindri :al rods 10 which are secured to the panels of the bar-- riers 1 and 2 by staples 11 or he like.

As disclosed in Figure 8, when two insulating panels 12 and 13 meet transversely so as to form a corner with their upper edges at substantially the same level they may be connected by metal strips 14 nailed or otherwise secured to said barriers as indicated at 15. It is a feature of the described construction, in any of the disclosed modifications thereof, that a very strong and rigid joint is established between the abutting barriers so that electrical instruments and switches and the like if mounted upon said barriers will not, through their weight, break the connection. Furthermore the construction is one that may be established very quickly and with comparatively slight expense.

It will further be noted that. my improved arrangement of barriers will provide faces without any exposed metallic fasteners, despite the fact that metallic fasteners are advantageously used to insure permanent maintenance of the barrier panels in their desired positions. The cement employed is formed of insulating material, and as far as possible of substantially the same ingredients as are embodied in the construction of the barriers themselves. The result is that high tension electric conductors, apparatus, etc, may be separated or completely surrounded by insulating barriers of high di-clectric properties, which barriers may be readily and conveniently erected from sections such as panels, slabs, etc., rigidly secured to each other.

While it will be apparent that the illus trated embodiments of my invention herein disclosed are well calculated to adequately fulfil the objects and advantages primarily stated, it is to be understood that the invention is susceptible to variation, modification and change within the spirit and scope of the subjoined claims.

What I claim is:

1. The combination with two substantially abutting insulating barriers, of a binding layer of cementitions material arranged between abutting faces of said barriers, and spaced anchorage members carried by both o! said barriers and projecting into said binding layer to rigidly connect both barriers to said. layer, said anchorage members having heads oi? greater area than the remainder ol said. members adapted to be embedded within said binding layer.

2. The combination with two substantially abutting barriers, each comprising a tier of insulating panels arranged on edge, oit' a binding layer of cementitious material arranged between said barriers, headed anchorage members carried by the panels of the barriers and extending alternately from each panel with their heads embedded within said binding layer, metal. strips extending through said binding layer in the joints between the panels of the two barriers, and spaced ta stening means rigidly securing said strips to both of said barriers.

In witness whereof I hereunto set my hand.

PAUL NICHOLAY.
